Working with tabs in Android using Fragments

Hey Guys,

Today i worked on tabs using fragments. And Always try to keep things simple as a like that way.

So here we go...

Since we have seen alots of examples which maintain fragment stacks manually using hashmaps and all . But i've read this from stackoverflow and other reference web sites about

fragmenttabhost so going to use this.

And thats how it works.

Base Classes :

1. AppMainTabActivity.java

public class AppTabBSecondFragment extends BaseFragment {

Button mBackbtn;

View mView;

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

mView = inflater.inflate(R.layout.app_tab_b_second_screen, container,

false);

initializeWidgets();

return mView;

}

private void initializeWidgets() {

mBackbtn = (Button) mView.findViewById(R.id.backbtn);

mBackbtn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

mActivity.handleBackPress();

}

});

}

2. BaseFragment.java

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;

public class BaseFragment extends Fragment {
public AppMainTabActivity mActivity;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

mActivity = (AppMainTabActivity) this.getActivity();
}

public boolean onBackPressed() {
return false;
}

public void onActivityResult(int requestCode, int resultCode, Intent data) {

}
}

Fragments which we are going to add in tabs and replace now

1. AppTabAFirstFragment.java

public class AppTabAFirstFragment extends BaseFragment {

private Button mGotoButton;

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.app_tab_a_first_screen, container, false);

mGotoButton = (Button) view.findViewById(R.id.id_next_tab_a_button);

mGotoButton.setOnClickListener(listener);

return view;

}

private OnClickListener listener = new View.OnClickListener(){

@Override

public void onClick(View v){

/* Go to next fragment in navigation stack*/

mActivity.mAddFragments(AppConstants.TAB_A, new AppTabASecondFragment(),true,true);

}

};

}

2. AppTabASecondFragment.java

public class AppTabASecondFragment extends BaseFragment {

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.app_tab_a_second_screen, container, false);

return view;

}

3. AppTabBFirstFragment.java

public class AppTabBFirstFragment extends BaseFragment {

private Button mGotoButton;

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.app_tab_b_first_screen, container, false);

mGotoButton = (Button) view.findViewById(R.id.id_next_tab_b_button);

mGotoButton.setOnClickListener(listener);

return view;

}

private OnClickListener listener = new View.OnClickListener(){

@Override

public void onClick(View v){

/* Go to next fragment in navigation stack*/

mActivity.mAddFragments(AppConstants.TAB_B, new AppTabBSecondFragment(),true,true);

}

};

}

4. AppTabBSecondFragment.java

public class AppTabBSecondFragment extends BaseFragment {

Button mBackbtn;

View mView;

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

mView = inflater.inflate(R.layout.app_tab_b_second_screen, container,

false);

initializeWidgets();

return mView;

}

private void initializeWidgets() {

mBackbtn = (Button) mView.findViewById(R.id.backbtn);

mBackbtn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

mActivity.handleBackPress();

}

});

}

5. AppTabCFirstFragment.java

public class AppTabCFirstFragment extends BaseFragment {

private Button mGotoButton;

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.app_tab_c_first_screen, container, false);

mGotoButton = (Button) view.findViewById(R.id.id_next_tab_C_button);

mGotoButton.setOnClickListener(listener);

return view;

}

private OnClickListener listener = new View.OnClickListener(){

@Override

public void onClick(View v){

/* Go to next fragment in navigation stack*/

mActivity.mAddFragments(AppConstants.TAB_C, new AppTabCSecondFragment(),true,true);

}

};

}

6. AppTabCSecondFragment.java

public class AppTabCSecondFragment extends BaseFragment {

Button mBackbtn;

View mView;

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

mView = inflater.inflate(R.layout.app_tab_c_second_screen,

container, false);

initializeWidgets();

return mView;

}

private void initializeWidgets() {

mBackbtn=(Button)mView.findViewById(R.id.backbtn);

mBackbtn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

mActivity.handleBackPress();

}

});

}

Now interface that i used to handle backpress normally :

1. BackButtonCallback.java

public interface BackButtonCallback {

void handleBackPress();

}

Now the constants class for this ....

1. AppConstants.java

public class AppConstants {

public static final String TAB_A = "tab_a_identifier";

public static final String TAB_B = "tab_b_identifier";

public static final String TAB_C = "tab_c_identifier";

}

And finally the XML layouts :

1. app_main_tab_fragment_layout.xml

Implementing Different Notifications in Android

Hey Guys,

I'm just providing a demo code for the newest notification going now a days in our android phones.

Try these methods and Enjoy new phase of notifications in development.

1. Set Normal Notification

private Notification setNormalNotification() {

Bitmap mNotificationPicture = null;

try {

mNotificationPicture = BitmapFactory

.decodeStream((InputStream) new URL(sample_url)

.getContent());

} catch (IOException e) {

e.printStackTrace();

}

// Setup an explicit intent for an ResultActivity to receive.

Intent resultIntent = new Intent(this, ResultActivity.class);

// TaskStackBuilder ensures that the back button follows the recommended

// convention for the back key.

TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

// Adds the back stack for the Intent (but not the Intent itself).

stackBuilder.addParentStack(ResultActivity.class);

// Adds the Intent that starts the Activity to the top of the stack.

stackBuilder.addNextIntent(resultIntent);

PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,

PendingIntent.FLAG_UPDATE_CURRENT);

return new NotificationCompat.Builder(this)

.setSmallIcon(R.drawable.ic_launcher)

.setAutoCancel(true)

.setLargeIcon(mNotificationPicture)

.setContentIntent(resultPendingIntent)

.addAction(R.drawable.ic_launcher, "One", resultPendingIntent)

.addAction(R.drawable.ic_launcher, "Two", resultPendingIntent)

.addAction(R.drawable.ic_launcher, "Three", resultPendingIntent)

.setContentTitle("Normal Notification")

.setContentText("This is an example of a Normal Style.")

.build();

}

Result :

2. Big Text Style Notification

private Notification setBigTextStyleNotification() {

Bitmap mNotificationPicture = null;

// Create the style object with BigTextStyle subclass.

NotificationCompat.BigTextStyle notiStyle = new NotificationCompat.BigTextStyle();

notiStyle.setBigContentTitle("Big Text Expanded");

notiStyle.setSummaryText("Nice big text.");

try {

mNotificationPicture = BitmapFactory

.decodeStream((InputStream) new URL(sample_url)

.getContent());

} catch (IOException e) {

e.printStackTrace();

}

CharSequence bigText = "This is a demo Big Text Style notification.This is a demo Big Text Style notification.This is a demo Big Text Style notification.This is a demo Big Text Style notification.This is a demo Big Text Style notification.This is a demo Big Text Style notification.This is a demo Big Text Style notification.";

notiStyle.bigText(bigText);

// Creates an explicit intent for an ResultActivity to receive.

Intent resultIntent = new Intent(this, ResultActivity.class);

// This ensures that the back button follows the recommended convention

// for the back key.

TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

// Adds the back stack for the Intent (but not the Intent itself).

stackBuilder.addParentStack(ResultActivity.class);

// Adds the Intent that starts the Activity to the top of the stack.

stackBuilder.addNextIntent(resultIntent);

PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,

PendingIntent.FLAG_UPDATE_CURRENT);

return new NotificationCompat.Builder(this)

.setSmallIcon(R.drawable.ic_launcher)

.setAutoCancel(true)

.setLargeIcon(mNotificationPicture)

.setContentIntent(resultPendingIntent)

.addAction(R.drawable.ic_launcher, "One", resultPendingIntent)

.addAction(R.drawable.ic_launcher, "Two", resultPendingIntent)

.addAction(R.drawable.ic_launcher, "Three", resultPendingIntent)

.setContentTitle("Big Text Normal")

.setContentText("This is an example of a Big Text Style.")

.setStyle(notiStyle).build();

}

Result :

notiStyle.setSummaryText("Nice big picture.");

try {

mNotificationPicture = BitmapFactory

.decodeStream((InputStream) new URL(sample_url)

.getContent());

} catch (IOException e) {

e.printStackTrace();

// Add the big picture to the style.

notiStyle.bigPicture(mNotificationPicture);

// Creates an explicit intent for an ResultActivity to receive.

Intent resultIntent = new Intent(this, ResultActivity.class);

// This ensures that the back button follows the recommended convention

// for the back key.

TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

// This is strictly for providing an example of multiple lines.

for (int i = 1; i <= 5; i++) {

notiStyle.addLine("(" + i + " of 6) Line one here.");

}

notiStyle.setSummaryText("+6 more Line Samples");

// This ensures that the back button follows the recommended convention

// for the back key.

TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

// Adds the back stack for the Intent (but not the Intent itself).

stackBuilder.addParentStack(ResultActivity.class);

// Adds the Intent that starts the Activity to the top of the stack.

stackBuilder.addParentStack(ResultActivity.class);

// Adds the Intent that starts the Activity to the top of the stack.

stackBuilder.addNextIntent(resultIntent);

PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,

PendingIntent.FLAG_UPDATE_CURRENT);

// Create remote view and set bigContentView.

RemoteViews expandedView = new RemoteViews(this.getPackageName(),

R.layout.notification_custom_remote);

expandedView.setTextViewText(R.id.text_view, "Neat logo!");

Notification notification = new NotificationCompat.Builder(this)

.setSmallIcon(R.drawable.ic_launcher).setAutoCancel(true)
